Description
Die Erfindung betrifft ein Flügelprofil für einen Savo niusrotor, der vornehmlich als Vertikalläufer zur Er zeugung elektrischer- und mechanischer Energie Verwen dung findet.The invention relates to a wing profile for a Savo niusrotor, primarily as a vertical rotor for Er generation of electrical and mechanical energy finds.
Bei der Erfindung handelt es sich um ein Element des Maschinenbaus.The invention is an element of Mechanical engineering.
Stand der Technik sind meist zwei- oder dreiblättrig flüglige Savoniusrotoren, deren Flügelflächen entweder, ob ihres labilen Aufbaus, zentral im Drehpunkt oder durch jenen hindurch zumindest diagonal verspannt werden müssen; oder Flügelprofile mit geringem Gesamt querschnitt, die zwar in der Lage sind, sich selbst zu halten, nicht jedoch befähigt sind, anfallende Strö mungsdifferenzen des Windes durch das Profil (z. B. durch Anwendung eines Darieusflügels) auch bei relativ niedriger Windgeschwindigkeit optimiert auszunutzen. Darieusrotoren, die relativ hoher Windgeschwindigkeiten - hohe Außendurchmesser - bedürfen, kleine Savonius rotoren dienen nur als Anlaufhilfe; Darieusrotoren werden ob ihrer hohen Drehzahlen nur zur Stromerzeu gung verwandt.State of the art are usually two or three-leaf winged Savonius rotors, the wing surfaces of which either whether its unstable structure, central in the pivot or strained through it at least diagonally Need to become; or wing profiles with low overall cross section, which are able to self hold, but are not able, currents differences in the wind caused by the profile (e.g. by using a Darieus wing) even with relative to take advantage of low wind speeds. Darieusrotoren, the relatively high wind speeds - high outside diameter - need small Savonius rotors only serve as a starting aid; Darieus rotors because of their high speeds, they are only used to generate electricity related.
Savoniusrotorflügel, bei denen die Druckdifferenz am Ende der Flügelblätter durch geeignete Maßnahmen zum optimierten Antrieb genutzt werden, sind dem Anmelder nicht bekannt.Savonius rotor blades, in which the pressure difference on Take appropriate measures to end the blades optimized drive are used, the applicant not known.
Der Erfindung liegt die Aufgabe zugrunde, einen ma terialsparend, einfach produzierbaren Savoniusrotor zu entwickeln, der nicht durch oder im Drehpunkt verspannt werden muß, der optimierte Laufeigenschaften gegenüber zentral verspannten Savoniusrotoren (durch Widerstandsverminderung der windentgegenrotierenden Flächen) aufweist und das Strömungsdruckgefälle beider Flügelseiten eines Einzelflügels beim Zusammentreffen der Strömungen nutzt.The invention has for its object a ma saves material, easy to produce Savonius rotor to develop that is not through or at the pivot must be braced, the optimized running properties opposite centrally tensioned Savonius rotors (through Resistance reduction of the counter-rotating wind Areas) and the flow pressure gradient of both Wing sides of a single wing when they meet who uses currents.
Grundlage der Erfindung sind das Savonius-Darieus- bzw. das Flettner-Prinzip.The basis of the invention is the Savonius-Darieus or the Flettner principle.
Um auf eine zentrale Abspannung zu verzichten, ist es vonnöten, den Profilquerschnitt der Einzelflügel weit zu erhöhen. Dieser wird nun statischen Ansprüchen gerecht, um auftretende Torsionsmomente im Betrieb auch bei großen Profillängen, also Savoniusrotorhöhen aufzu nehmen.In order to do without central bracing, it is the profile cross-section of the individual wings to increase far. This now becomes static justice to torsional moments occurring during operation too with large profile lengths, i.e. Savonius rotor heights to take.
Bei großen Profilquerschnitten ergibt sich im Rotations zustand, bei dem die Innenströmungslinie (2) windab gewandt, die Außenströmungslinie (3) dem wahren Wind zugewandt ist, eine starke Strömungsdifferenz am Flügelende im Raum (A) zwischen, durch mehrmalige Ab lenkung stark abgebremstem wahren Innenwind und durch seitliche Verdrängung stark erhöhtem Außenwind.In the case of large profile cross-sections, there is a strong flow difference at the wing end in space (A) between, with the inner flow line ( 2 ) facing away from the wind and the outer flow line ( 3 ) facing the true wind, due to repeated deflection of the braked true inside wind and greatly increased outside wind due to lateral displacement.
Je höher das Profil, desto höher der Strömungsunter schied; es gilt also, den Profilquerschnitt so hoch wie möglich zu gestalten um einen größeren Strömungs unterschied im Raum (A) zu erreichen.The higher the profile, the higher the flow sub divorced; so it is important to have a high profile cross section as possible to create a larger flow difference in room (A).
Anders herum müssen Tests im Windkanal erweisen, ab welcher Profilhöhe des Einzelflügels der Einfluß des Windschattens des wahren Windes auf das vorlaufende Profil negativ wirkt und der Vorteil größeren Profil querschnitts mit dem Nachteil größerer, also schnellerer Wirkung des Windschattens auf den Vor flügel ausgewogen sind; wobei bei dreiflügligen Savoniusrotoren eine unumgängliche Strömungsverwirbe lung im Raum (C) entfällt und den Wirkungsgrad dadurch erhöht.The other way round, tests in the wind tunnel have to prove what profile height of the single wing the influence of Slipstream of the true wind on the leading Profile has a negative effect and the advantage of a larger profile cross-section with the disadvantage of larger, so faster impact of slipstream on the fore wings are balanced; being three-winged Savonius rotors are an inevitable flow swirl tion in room (C) is eliminated and the efficiency is reduced elevated.
Der Profilschwerpunkt muß sich möglichst nah am Dreh punkt (M) und am vorlaufenden Flügel befinden, um zu den Enden hin eine möglichst lange effektive Strömungs-Ver drängungslinie zu erhalten; jedoch den Raum (B) nicht stören.The focus of the profile must be as close as possible to the rotation point (M) and on the leading wing to reach the End effective flow Ver as long as possible to get crowding; but not the room (B) to disturb.
Dieses Strömungsgefälle zwischen Außen- und Innenströ mung, das variiert, da die Innenströmungslinie (2) ab wechselnder Strömungsrichtung durch Rotation des Savoniusrotors ausgesetzt ist, wird normalerweise einen Sog entwickelnd, ungenutzt hinter der Strömungskante ver wirbeln, was wir jedoch zum Beispiel durch Anbringen eines asymmetrischen Flügels (4) im Grenzbereich Raum (A) zu verhindern wissen.This flow gradient between the outside and inside flow, which varies because the inside flow line ( 2 ) is exposed from the changing flow direction by rotation of the Savonius rotor, will normally develop a suction, swirl unused behind the flow edge, which we, for example, by attaching an asymmetrical Knowing how to prevent wing ( 4 ) in the border area room (A).
Es muß sich erweisen, auf welcher Profilseite die Parallel-Steigungs-Anströmungswinkelverstellungen des asymetrischen Darieusflügels (bzw. Flettnerrotors) (4a, 5a) gebracht werden müssen, da auf der Innenseite (2) ein zu frühes Abbremsen des wahren Windes bei dessen Einfall auf der Rückseite (3) ein zu starkes Abbremsen der dortigen, verstärkten Verdrängungsströmung erreicht wer den kann, was jedoch ihres nur vereinzelten Vorkommens im Verhältnis zur Gesamtprofillänge wahrscheinlich uner heblich ist.It has to be shown on which profile side the parallel pitch-flow angle adjustments of the asymmetrical Darieus wing (or Flettner rotor) ( 4 a, 5 a) have to be made, because on the inside ( 2 ) the real wind is braked too early when it falls on the back ( 3 ) a too slow braking of the local, displaced flow achieved who can, which, however, their only occasional occurrence in relation to the overall profile length is probably irrelevant.
Im Falle, in dem die Strömungslinie (2) dem wahren Winde zugeneigt ist, wird natürlich die Wirkung des Darieus-Flügels (4) nachlassen, jedoch die Windangriffs fläche und ausgelöstes Drehmoment, durch Vergrößerung des effektiven Rotordurchmessers im Vergleich zu Ro toren ohne Darieus-Flügel, verbunden mit besserer Stabilität, größer sein, wobei der Effekt auftreten kann, bei dem die äußere - nach außen strömende "Hoch druckzone" die effektive Profillänge so vergrößert, daß schwächerer wahrer Wind gegenläufig an der Hochdrucklinie (verlängerte 3er Linie) entlang in den Rotor einfällt.In the case where the flow line ( 2 ) is inclined to the true wind, the effect of the Darieus wing ( 4 ) will of course decrease, but the wind attack area and the torque triggered, by increasing the effective rotor diameter compared to rotors without Darieus. Wings combined with better stability can be larger, whereby the effect can occur in which the outer - outward flowing "high pressure zone" increases the effective profile length in such a way that weaker true wind flows in opposite directions along the high pressure line (extended 3 line) into the Rotor collapses.
Dynamischer Auftrieb des Hauptflügelprofils (1) ist wohl nur bei zweiblättrigen Savoniusrotoren zu erwarten, da bei dreiblättrigen eine Strömungstrennung im Bereich Raum (C), einerseits nach außen, andererseits zum Dreh punkt hin, zu erwarten ist.Dynamic lift of the main airfoil ( 1 ) is probably only to be expected with Savonius rotors with two blades, since with three blades a flow separation in the area (C), on the one hand outwards and on the other hand towards the pivot point, is to be expected.
Die Innenabströmkante (7) muß möglichst scharfkantig ausgeführt werden, um keine Strömungsverluste durch Ver wirbelungen hervorzurufen.The inner trailing edge ( 7 ) must be as sharp as possible, so as not to cause flow losses due to swirling.
Bei zweiblättrigen Savoniusrotoren kann es nützlich sein, Ausgleichsgewichte (6) rückenflossenartig auf dem Flügelprofil (1) zu ermöglichen.In the case of Savonius rotors with two blades, it can be useful to enable balance weights ( 6 ) on the wing profile ( 1 ) in the manner of a dorsal fin.
Außerdem ist eine bessere Laufeigenschaft im Vergleich zu innenverspannten Savoniusrotoren schon deshalb zu erwarten, da die Windangriffsfläche der Strömungslinie (3) strömungsgünstiger als die ansonsten als Innen- und Außenlinie verwandte Linie (2) wirkt und zusätzlich Verwirbelungen an Abspannungen, oder - und dann nötigem Zentralrohr entfallen.It is also for this reason to expect a better running property as compared to an internally braced Savoniusrotoren because the wind surface of the flow line (3) acts streamlined than otherwise related as interior and exterior line line (2) and additionally turbulence at bracing, or - and then nötigem central tube omitted.
Der Darieusflügel wird ob des verdrängten wahren Windes und der Druckgefälleausnutzung viel früher, d. h. bei viel schwächeren wahren Winden Schub entfalten, als reine Darieusrotoren trotz geringeren Gesamtdurch messers des Rotors. The Darieus wing becomes because of the repressed true wind and pressure drop utilization much earlier, i.e. H. at thrust much weaker true winds than pure Darieus rotors despite lower overall through knife of the rotor.
Merkmale der Erfindung sind:Features of the invention are:
Große Effektivität durch optimierte Verbindung des Savonius- mit dem Darieus- bzw. Flettnerprinzips.Great effectiveness through optimized connection of the Savonius with the Darieus or Flettner principle.
Sich selbst frei tragende hocheffiziente Einzelflügel, die leicht in jeder beliebigen Länge, material-, energiesparend, allen statischen Kräften gewachsen, produziert werden können.Self-supporting, highly efficient single wings, which are light in any length, material, energy-saving, able to withstand all static forces, can be produced.
Die Flügel können, auf geeigneten Gitterkonstruktionen gehalten, an Trägerrahmen oder vorhandenen Türmen be festigt, bzw. was mir sinnvoller erscheint, frei abge spannt werden.The wings can, on suitable lattice constructions held, be on support frames or existing towers consolidates, or what seems more meaningful to me, freely given be stretched.
Die Herstellung kann im Vakuumverfahren (Epoxy, Sperr holz, Triaxialgewebe, Kohle-, Aramid-Faser, etc.), oder als Endlosprofil, das nur in jeweiliger Länge gekappt wird, erfolgen.The production can be done in a vacuum process (epoxy, barrier wood, triaxial fabric, carbon, aramid fiber, etc.), or as an endless profile that is only cut to length will be done.
Große Sicherheit und Variabilität durch starke Profile und der Möglichkeit, die Savoniusrotordrehzahl durch Einstellungswinkelverstellung des Darieusflügels, bzw. Drehrichtungs- oder Umdrehungszahlveränderung des Flettnerrotors, den Rotor abzubremsen (z. B. bei Stark wind); oder die Rotationsgeschwindigkeit so dem Ge brauchszweck (Verbraucher) bei jeder Windgeschwindigkeit optimal anzugleichen; bzw. Möglichkeit, über die Darieusflügeleinstellung (5a) ähnlich dem "Giro-Mill- Prinzip" (Just) bei stärkeren Winden durch gleichför mige Verstellung im Rotationsprozeß, die Auftriebs spitzen der Darieusflügel gegen die wahre Wind-Richtung zu verlagern und so die Abspannung zu entlasten und das Gesamtsystem zu stützen. Great safety and variability thanks to strong profiles and the option of braking the rotor of the Savonius rotor by adjusting the setting angle of the Darieus wing or changing the direction of rotation or speed of rotation of the Flettner rotor (e.g. in strong winds); or to optimally adapt the speed of rotation to the intended use (consumer) at any wind speed; or possibility of using the Darieus wing setting ( 5 a) similar to the "Giro Mill Principle" (Just) in stronger winds by uniform adjustment in the rotation process, the buoyancy tips of the Darieus wings to shift against the true wind direction and thus the guy to relieve and support the entire system.
Des weiteren ist durch die großen Hauptflügelquer schnitte (1) genügend Raum vorhanden, durch einfach realisierbaren Druckabfall im Inneren der Tragflächen, (1) Grenzschichtabsaugung realisierbar.Furthermore, due to the large main wing cross-sections ( 1 ) there is enough space, through an easily realizable pressure drop inside the wings, ( 1 ) boundary layer suction can be realized.
Wartung erfolgt durch einfache Demontage-Montage weniger stabiler Teile.Maintenance is carried out by simple disassembly assembly less stable parts.
